Claims.

The present application is a division of the applicants applicationSerial No. 402,024, filed October 24, 1929, and relates to a particularmeans for clamping individual type slugs in a y, printing block which,while capable of general usage, is particularly adaptable for use in themachine forming the subject matter of the above noted parentapplication.

The construction and operation of the type clamp forming the subjectmatter of the present application will be fully disclosed hereinafter,reference being had to the accompanying drawing, of which:

Fig. 1 is a perspective View of a type block and slug clamp made inaccordance with the principles of the invention; and

Fig. 2 is a sectional View taken on the line 2--2, Fig. l.

As shown in the drawing, the type slugs |130 are of a T-type and areadapted to be clamped in printing position in a type block i3 l.

As shown in the drawing, the type block |3| in the present case issegmental in form. On the outer surface of the type block |3| areradially extending typereceiving grooves |35 into which are adapted tofit fins or lugs |35 which are formed integral with the cross or faceplate |31 of the T-shaped type slugs li.

The type-receiving grooves 35 are substantially equally spaced aroundthe periphery |38 of the type block. Between each successive pair ofgrooves 35 is a radially extending groove |39 which provides a fin |46adjacent one side of each of the type-receiving slots or grooves |35. Atthe opposite side oi each of the type-receiving grooves |35 is formed arelatively heavy and rigid portion |4|.

At spaced intervals along each of the grooves |39 the type block |3| isprovided with tapered openings |42 which terminate in threaded openings|43 formed in the base or ungrooved inner portion |44 of the type block|3|. The threaded openings |43 are adapted to receive correspondinglythreaded screw members |45 which have frusto-conical heads |46 which areadapted to move axially into the tapered openings |42 when the screws|45 are tightened and thereby spread the relatively thin and more orless flexible portions |4|l in opposite directions toward their adjacenttype-receiving grooves |35, which reduces the width of the saidtype-receiving grooves and thereby clamps the ns |35 of the type slugsrespectively within the said type-receiving grooves |35 with the faceplate |31 of each slug resting firmly on the outer face |38 of the block|3l.

Obviously, the type block |3| may be flat instead of being curved incross section for use in a flat bed machine instead of a curved bed orcylinder machine such as that disclosed in the above noted parentapplication without departing from the spirit of the invention.

I claim:

1. A type block having a type-receiving groove formed between a rigidwall and a relatively movable wall, a series of individual type slugsindependently slidable to different positions in and along said groove,and means at predetermined relatively closely spaced pointslongitudinally of said groove for iiexing the movable wall toward therigid wall to clamp said type slugs therebetween.

2. A type block having a pair of substantially parallel type-receivinggrooves, the outer walls of which are rigidly disposed in relation toeach other and the inner walls of which are movable relative to saidouter Walls, a series of individual type slugs independently slidable todifferent positions respectively in at least one of said grooves, andmeans disposed intermediate said inner walls at predetermined relativelyclosely spaced points longitudinally of said grooves for spreading thesame toward the said outer walls respectively to clamp said individualslugs in their adjusted positions respectively.

3. A type block having a pair of substantially parallel type-receivinggrooves, the outer walls of which are rigidly disposed in relation toeach other and the inner walls of which are movable relative to saidouter walls, a series of individual type slugs independently slidable todiierent positions respectively in at least one of said grooves, saidblock having a third groove intermediate said type-receiving grooves,and a series of wedge elements adapted to said third groove atrelatively closely spaced points along said third groove for spreadingthe said inner walls for the type-receiving grooves toward the saidrigid walls thereof to clamp said individual slugs in their adjustedpositions respectively.

4. A type block having a pair of substantially parallel type-receivinggrooves, the outer walls of which are rigidly disposed in relation toeach other and the inner walls of which are movable relative to saidouter walls, said block having a third groove intermediate saidtype-receiving grooves, and a plurality of tapered openings spaced alongand aligned with said third groove,

and tapered elements adapted to be forced into said tapered openings.

5. A type block havingra pair of substantially parallel type-receivinggrooves, the outer Walls of which are rigidly disposed in relation toeach other and the inner Walls of which are movable relative to saidouter Walls, said block having a third groove intermediate saidtype-receiving grooves, and a plurality' of circular tapered holesgrooves toward the said outer Walls thereof respectivelyl y A CHARLES J.BECK.
